Who are the living characters?
What houses do they belong to?
Where they physically are at the moment?
What fights are out there between them?

Book readers have the source material books to reference. TV viewers only (like myself) have just their recollection. Since this show continues to expand in characters and places it demanded that I committed to myself to put this to paper to keep in straight. Perhaps this can be helpful to you as well so I am sharing this.

What if characters don't have a permanent home or out on travel? (See 'Groups Out on Travel Section'.)

Why aren't dead characters listed in locations?
(It's not necessary since they are dead. However, they are sources of fights though. I may make a dead thread for GOT by house. Putting it here makes the quick reference guides hard to read.)

Why is Orell counted as alive? He is a Warg and cheated death by Warging into an eagle before his body was killed.

This is a living document to run up through Season 4. Wikias have way too much information and can spoil things and I wanted to reference (as I watch) a concise form and came up with this.

Please let me know of any corrections or additions and I will update this information. From here forward, I will save a version of this after each episode. Unfortunately I don't have time to go backwards and do this for every episode prior.

Examples on how you can interpret this thread:

#1: We know Myrcella, Tommen are illegitimate children of Cersei Baratheon and Jaime Lannister and they have been split up. Therefore you will see their names in three places (House of Baratheon, Lannister and also under House of Martell.)

#2: Winterfell; although abandoned is left as capital of The North although that has shifted to Dreadfort (House of Bolton). Winterfell was capital for thousands of years. It's unclear what House Bolton intends. The North is in utter chaos now...

#1: Arya and the Hound: @Arya, @Hound;
(Last seen in The Riverlands; learning how to fight with armor.)

#2: Benjen's Scout party: @Benjen (?);
(Last seen ranging North of the Wall. His horse came back; not him. Two members of his party were found dead and one resurrected as a wight which Jon Snow dealt with.)
